Separation Model

Reliable acrylic retainer workflow with Separator-Free 3D-Printing resin

Most 3D‑printing model resins are built on acrylate and methacrylate backbones. Because these resins share the same chemical “DNA” as traditional ortho‑acrylic (PMMA), they form strong chemical bonds during fabrication. For a dental lab, this chemical bond is a major headache during appliance fabrication. When a dental laboratory receives a digital scan, they print the arch and prep it for a (Hawley) retainer or bite plate. Traditionally, this requires carefully applying a separating agent or isolating medium on the 3D-printed model. If you’ve spent time at the bench, you know the risks:

• – Wasted Bench Time: Applying and drying separators slows down your turnaround time.

• – The missed spot: If you miss even a small spot, the cold-cure or self-cure acrylic will fuse permanently to the 3D-printed model.

• – Failed Breakouts: Trying to pry a fused retainer off a model usually ends in a loud crack—forcing you to restart the entire salt-and-pepper process from scratch. Additionally you need to produce a new model before preparing the new retainer.

Liqcreate has engineered a specialized dental model resin designed for the orthodontic and prosthetic workflow. Unlike standard resins, this new chemistry features inherent non-stick properties toward orthodontic and prosthetic acrylics. By removing the need for a separating medium, it streamlines the digital‑to‑analog workflow

1. Print & Post-Cure: Process the model as usual.

2. Straight to Acrylic: Fabricate your prosthetic or ortho‑acrylic appliance right on the 3D-printed model—no separating medium required.

3. Clean Release: The finished device pops off the model effortlessly after polymerization in the pressure pan.

By removing the manual step of coating models, this eliminates the single most common cause of appliance failure during the breakout phase. Increase your lab’s output, reduce material waste, and stop worrying about fused PMMA retainers to 3D-printed models.
